Connecting UniOP to Mitsubishi Q Series with Ethernet
unable
This Technical Note contains the information needed to connect UniOP to Mitsubishi Q Series controllers using an Ethernet connection to the Ethernet module in the PLC.
The Mitsubishi Q Ethernet communication driver is delivered with the Designer file D32uplc205.dll.

1 Introduction
To create a Designer project for Ethernet communication to the Mitsubishi Q Series, select the driver “Mitsubishi Q ET” from the list of drivers in the Configure Controller… dialog box.
The Series Q controller must be equipped with an appropriate Ethernet interface. The following Ethernet communication modules can be used for communication:
QJ71E71-100
The operator panel must be equipped with the optional SCM11 communication module to support Ethernet TCP/IP communication.
UniOP currently supports only 10 Mb Ethernet over twisted pair.
Note:The TCM10 Ethernet module cannot be used for connection to the Mitsubishi Q SeriesPLCs.
2 Configuration with Designer
The UniOP project file must be properly configured for Ethernet communication with Mitsubishi controllers.
2.1 Panel Setup
The UniOP panel must be assigned a unique IP address.
There are multiple ways to assign an IP address to the panel; please refer to the User’s Manual for detailed instructions.
The “Ethernet Board” option must be enabled in the Panel Setup dialog box under the tab “External Devices”.
The panel IP address may be defined in the field “Ethernet Board” as shown in Figure 3 below.
Figure 1 – IP Address in Panel Setup
If the field contains the IP address 0.0.0.0, then the panel will derive the IP address using one of the alternate methods.
2.2 Controller Setup
Figure 2 shows the Designer Controller Setup dialog box for the Mitsubishi Q ET driver.
The Ethernet IP address of the controller connected to the operator panel must be entered in the “IP address” field.
The field “Port” contains the port number used in the communication with the PLC. Most application will use the default value.
Figure 2– Controller Setup dialog box
The protocol implementation supports the connection of multiple controllers to one operator panel, as shown in Figure 3. To set-up multiple connections, check the “Access Multiple Drives” checkbox in the Controller Setup dialog box, see Figure 2.
Figure 3– Multiple controller connection
Depending on the PLC configuration, there is also the possibility to connect more than one panel to the same controller. Please refer to the Mitsubishi manual for instructions about how to configure the number of available connections.
2.3 RDA Setup
The Real Time Clock information in the Reserved Data Area (RDA) is coded in binary and is arranged as shown in Table 1.
Dn 0 Day of the week
Dn+1 Day Month
DBn+2 Year Hour
DBn+3 Minutes Seconds
Table 1. RTC information in the RDA
The page number displayed and the page number requested in the RDA are coded in binary.
The RDA can be freely positioned within the Data Registers in the PLC memory.
For the parts of the RDA organized in bits (Keyboard Status, LED Control, Alarms, UniOP Status Word and PLC Command Word), the first bit in the RDA corresponds to the first bit in the PLC (i.e. the LSB bit in the register). For example, if the Keyboard Status area is positioned at address D0, the
n the key F1 will be mapped to bit 0, the key F8 will be mapped to bit 7 and so on as listed in Table 2.
